Can someone help me please, i understand everything but one thing what may make me come across stupid.

is there a certain type of diodes to use?

i need to purchase them soonish but one website tells me to use 1N914, another tells me to use 1N4148 and another one tells me to use both :S

Going by this image:


what ones do i need and what one will go on the yellow and what one will go on the blue?

never used diodes before in my life so i dont know what one i need.

Thanks for any help.

The diodes for both the yellow and blue line are 1N914/1N4148 (they are switching diodes).  I bought my 10 pack of those diodes at RadioShack for $1.49.  On each diode, there is a dark/black strip, which is direction to solder diode on that Xenon diagram.

Hello, thanks for your help.

this is the one i think you have: http://www.radioshac...oductId=2062587

im in the UK and on either ebay or maplins all i can find is one or the other :S

http://www.maplin.co...?ModuleNo=46386 - not too sure what that is

http://cgi.ebay.co.u...4#ht_1403wt_952 - 1N914 switching diode, no mention of 1N4148

and

http://cgi.ebay.co.u...d#ht_3175wt_970 - 1N4148 Switching diode, no mention of 1N914

Please help me out here, Diodes aren't my thing


Thanks

Liam

A 1N914 diode is the same as a 1N4148.  Even if it does not mention that it's a switching diode, it probably is b/c their is an International Standard and naming convention that are followed when creating the components.

I got write errors with nandpro when using this wiring and the J2D2.4->J2D2.7 was soldered.
I disconnected the J2D2.7 wire and after that the nandpro write operation worked again.

I had no such problems when using the 3x330ohm in place on another xenon board.

Has it relevance or is it just solar flares messing with my lpt rig today..?
Did not reflash with J2D2.7 connected to verify problem after that, as I got it working.

so yeah i went in and did all the soldering and got the cant find flash error so i rewired everything and now its telling me could not open virtual nand device file: ltp could not continue and i cant figure this out help would be appreciated.

Are you using the latest nandpro? I think they have remove the virtual nand function, use the older version.

Hi Guys

I've done a couple of jtags using this method and didn't have any problems until today.  One that I tagged a couple of days ago is throwing an E79 error.  I won't bore you with all the checks I have done but I am now checking the diodes with the diode setting on my multimeter.  Can anybody confirm if the values that I am getting are correct:

337 @ point 3 below
-422 @ point 4 below



Cheers
